Step 19 of 81

To double-check that the system is off, adjust the temperature with your current thermostat.

Step 20 of 81

Wait a few minutes to make sure your system doesn't turn on. Turning the power off may disable Wi-Fi, so make sure your phone has mobile data turned on.

Step 21 of 81

Next, follow the steps in the app to remove the front of your thermostat and check the type of system you have.

Step 22 of 81

If you see 120V or 240V labels, stranded wires, or thick wires with wire nuts, your system is high voltage and not compatible with the Nest Learning Thermostat.

Step 23 of 81

Important! Do not connect a Nest Learning Thermostat to these high voltage wires.

Step 24 of 81

If your system is compatible, tap Not High Voltage.

Step 25 of 81

Take a picture of the wires with your phone. This will be useful for reference later.

Step 26 of 81

If there are jumper wires connecting one wire to another, loosen the screws to remove them.

Step 27 of 81

You won't need them. Some thermostat terminals may have two labels, one for conventional systems and one for systems with a heat pump.

Step 28 of 81

If your terminals have two labels, tap Yes.

Step 29 of 81

Otherwise, tap No. Identify and select the type of wires your thermostat has.

Step 30 of 81

Depending on the type of wires you have, the app may walk you through additional steps.

Step 31 of 81

Step 32 of 81

With the power still off, remove the wires from the terminals one at a time and attach the matching sticker label provided in your thermostat box.

Step 33 of 81

Most thermostats have screws that hold the wires in. Use a screwdriver to disconnect them.

Step 34 of 81

Other thermostats may have buttons that you simply press to release the wires.

If you're not installing the trim plate, tap No.

Step 39 of 81

Gently pull the wires through the thermostat base.

Step 40 of 81

Use the bubble level to make sure the base plate is straight. Then mark where the screws will go.

Step 41 of 81

To attach the base plate to the wall, use the long pointed screws that came in the box.

Step 42 of 81

If you are installing in drywall, use anchors.

Step 43 of 81

If you need to drill holes in your wall, remove the base plate before doing so.

Step 44 of 81

Pre-drill a hole with a 3/32 inch or 2.5 mm drill bit.

Step 45 of 81

Tighten the screws until the base plate is firmly against the wall.

Step 46 of 81

Use the bubble level to make sure it's straight. Untangle the wires and align them with the terminals, but don't insert the wires yet.

Step 47 of 81

Check the ends of your thermostat wires. They should be straight.

Step 48 of 81

If not, re-strip them and trim the ends, leaving 3/8 of an inch or 10 mm of wire exposed.

Step 49 of 81

Use the on-screen diagram as a wire guide. Starting from the top, hold each lever all the way down while inserting the wire into the correct terminal.

Step 50 of 81

When the wire is secure, the lever will remain pressed.

Step 51 of 81

Push in the wires so they're flush with the back plate, and make sure the levers stay pressed when the wires are gently pulled or adjusted.

Step 52 of 81

This lets you attach the display properly. If the levers don't remain pressed, strip the wire a bit more.

Step 53 of 81

Then, reinsert the wire. To attach the display, align the display and base.

Step 54 of 81

Then press evenly along the entire edge of the display until it clicks into place.

Step 55 of 81

Now go to the circuit breaker and turn the power back on.

Step 61 of 81

If not, turn your power off and check that you've inserted the wires into the right connectors, and make sure they're pushed all the way in.

Step 62 of 81

Next, the app will test the installation to make sure your thermostat is getting enough power.

Step 63 of 81

Follow the on-screen steps to tell your thermostat a few more things about your system.
